Harnessing Phytochemicals for Brain Cancer Therapy: Insights Into Medulloblastoma and Glioblastoma Treatment

Phytochemical Analysis, Volume 37, Issue 4, Page 507-535, June 2026.
ABSTRACT Primary brain tumors are life‐threatening diseases. Glioblastoma is the most aggressive type with a poor prognosis. Medulloblastoma is the most common pediatric brain tumor. While surgical treatments often result in recurrences owing to the complex nature of the tumor microenvironment, conventional treatments lower the quality of life of ...

A conserved amino acid residue critical for product and substrate specificity in plant triterpene synthases

, 2016
Triterpenes are structurally complex plant natural products with numerous medicinal applications. They are synthesized through an origami-like process that involves cyclization of the linear 30 carbon precursor 2,3-oxidosqualene into different triterpene

Investigation of the potential for triterpene synthesis in rice through genome mining and metabolic engineering

, 2011
The first committed step in sterol biosynthesis in plants involves the cyclization of 2,3-oxidosqualene by the oxidosqualene cyclase (OSC) enzyme cycloartenol synthase. 2,3-Oxidosqualene is also a precursor for triterpene synthesis.
